Abstract :
A multi-CCD method is described, which depends mostly on software and makes use of digital signal processing to clean the aliased component of frequency spectrum of under sampled images. The acquisition method for high resolution images consists mainly of image registration and reconstruction. Two corresponding algorithms, gradient registration based on spline multiresolution approximation and reconstruction of weighted spline interpolation, are suggested respectively
